网络监控：Smokeping

最近工作中需要监测某个分公司到IDC机房的网络情况，到网络上找了不少软件，发现一款叫smokeping的开源软件还不错，它是rrdtool的作者制作的，在图形显示方面很漂亮，可以用来很好的检测网络状态和稳定性。

下面介绍一下软件的安装配置方法：

一．安装软件 

1.使用yum 命令安装所需的工具 

 yum install gcc freetype-devel zlib-devel libpng-devel libart_lgpl-devel httpd-devel apr-util-devel apr-devel cairo cairo-devel pango pango-devel libxml2 libxml2-devel perl-XML-Simple.noarch perl-Crypt-SSLeay perl-Digest-HMAC

2. 安装rrdtool 

wget http://oss.oetiker.ch/rrdtool/pub/rrdtool-1.3.6.tar.gz 
tar zxvf rrdtool-1.3.6.tar.gz 
cd rrdtool-1.3.6 
./configure --disable-tcl 
make 
make install

3. 安装cgilib 

wget http://down1.chinaunix.net/distfiles/cgilib-0.5.tar.gz 
tar zxvf cgilib-0.5.tar.gz 
cd cgilib-0.5 
make 
cp libcgi.a /usr/local/lib 
cp cgi.h /usr/include

4. 安装fping 

wget http://fping.sourceforge.net/download/fping.tar.gz 
tar zxvf fping.tar.gz 
cd fping-2.4b2_to 
./configure 
make 
make check 
make install

5.安装 echoping 

wget http://jaist.dl.sourceforge.net/project/echoping/echoping/6.0.0/echoping-6.0.0.tar.gz 
tar zxvf echoping-6.0.0.tar.gz 
cd echoping-6.0.0 
./configure 
make 
make test 
make install

6.安装 CGI-SpeedyCGI 

wget ftp://195.220.108.108/linux/epel/5/x86_64/mod_speedycgi-2.22-4.el5.x86_64.rpm 
wget ftp://ftp.muug.mb.ca/mirror/fedora/epel/5/x86_64/perl-CGI-SpeedyCGI-2.22-4.el5.x86_64.rpm 
rpm -ivh --force perl-CGI-SpeedyCGI-2.22-4.el5.x86_64.rpm 
rpm -ivh mod_speedycgi-2.22-4.el5.x86_64.rpm 
wget http://mirrors.163.com/cpan/authors/id/H/HO/HORROCKS/CGI-SpeedyCGI-2.22.tar.gz 
tar zxvf CGI-SpeedyCGI-2.22.tar.gz 
cd CGI-SpeedyCGI-2.22 
perl Makefile.PL 
遇到问题选择默认选项（no） 
make 
make test 
make install

7.安装smokeping 

wget http://oss.oetiker.ch/smokeping/pub/smokeping-2.3.6.tar.gz 
tar zxvf smokeping-2.3.6.tar.gz 
mv smokeping-2.3.6 /usr/local/smokeping 
cd /usr/local/smokeping

二．配置smokeping 

1. 修改文件名 

修改/usr/local/smokeping/bin下的smokeping.dist 
cp smokeping.dist smokeping 
修改etc/ 下的 basepage.html.dist，config.dist，smokemail.dist 
cp basepage.html.dist basepage.html 
cp config.dist config 
cp smokemail.dist smokemail 
chmod 600 smokeping_secrets.dist 
修改htdoc/下的smokeping.cgi.dist 
cp smokeping.cgi.dist smokeping.cgi

2. 修改配置文件

配置 bin/smokeping 
vi /usr/local/smokeping/bin/smokeping 
在这个文件里面我们需要修改前面两个 lib 和后面 config 文件的 path。 
两个 lib 分别是 smokeping 的 lib 和 rrdtool 的 lib （红色为修改后的内容） 

#!/usr/sepp/bin/perl-5.8.4 -w 
#!/usr/bin/perl -w 
use lib qw(/usr/pack/rrdtool-1.2.23-mo/lib/perl); 
use lib qw(/usr/local/rrdtool-1.3.6/lib/perl); 
use lib qw(lib); 
use lib qw（/usr/local/smokeping/lib); 
use Smokeping 2.003006; 
Smokeping::main("etc/config.dist"); 
Smokeping::main("/usr/local/smokeping/etc/config"); 

配置 htdocs/smokeping.cgi,方法与上面相同  

 

vi /usr/local/smokeping/htdocs/smokeping.cgi 
************************ 
#!/usr/sepp/bin/speedy -w

#-*-perl-*- 
#!/usr/bin/speedy -w 
# -*-perl-*- 
# use lib qw(/usr/pack/rrdtool-1.0.33-to/lib/perl); 
use lib qw(/usr/local/rrdtool-1.3.6/lib/perl/); 
# use lib qw(/home/oetiker/data/projects/AADJ-smokeping/dist/lib); 
use lib qw(usr/local/smokeping//lib); 
use Smokeping 2.003006; 
Smokeping::cgi("/home/oetiker/data/projects/AADJ-smokeping/dist/etc/config"); 
Smokeping::cgi("/usr/local/smokeping/etc/config");

 

配置 etc/config 

vi usr/local/smokeping/etc/config   将以下几行替换为已经安装的相关软件的路径 
*** General *** 
imgcache = /home/oetiker/public_html/smokeping-ms/cache 
imgcache = /usr/local/smokeping/htdocs/cache 
imgurl = cache 
imgurl = cache 
datadir = /tmp/smokeping-ms/data 
datadir = /usr/local/smokeping/var 
piddir = /tmp/smokeping-ms/var 
piddir = /usr/local/smokeping/var 
cgiurl = http://some.url/smokeping.cgi 
cgiurl = http://本机IP/htdocs/smokeping.cgi ; 
smokemail = /home/oetiker/checkouts/smokeping/trunk/software/etc/smokemail.dist 
smokemail = /usr/local/smokeping/etc/smokemail 
tmail = /home/oetiker/checkouts/smokeping/trunk/software/etc/tmail.dist 
tmail = /usr/local/smokeping/etc/tmail.dist 
*** Presentation *** 
template= /home/oetiker/checkouts/smokeping/trunk/software/etc/basepage.html.dist 
template = /usr/local/smokeping-2.3.6/etc/basepage.html 
*** Probes *** 
+ FPing 
binary = /usr/sbin/fping 
binary = /usr/local/sbin/fping 
#** Database *** 
step = 60 
pings = 10

修改ping的频率，默认为300秒ping20 次，我们可以根据需要调整，这里修改为60秒 ping 10次。 
*** Targets *** 

#================================= 
#这里用于配置监控目标，以+号分层,+为首页，++为子层，我们以百度和搜狐为例。 
+TEST              
menu= TEST 
title = TEST 
++ baidu         
menu = baidu 
title = baidu 
host = 115.239.210.27 
++ sohu 
menu = sohu 
title = sohu 
host = 121.14.0.97 
#================================= 

3. 添加目录

建立下面三个目录用于保存smokeping的数据等

mkdir /usr/local/smokeping/data
mkdir /usr/local/smokeping/var
mkdir /usr/local/smokeping/htdocs/cache
chown –R apache:apache /usr/local/smokeping

4. 修改apache配置文件

vi /etc/httpd/conf/httpd.conf 
添加下面内容： 
Alias /smokeping/ "/usr/local/smokeping/htdocs/" 
Alias /cache/ "/usr/local/smokeping/cache/" 
<Directory "/usr/local/smokeping/htdocs"> 
Options FollowSymLinks ExecCGI 
AllowOverride None 
AddHandler cgi-script cgi 
Order allow,deny 
Allow from all 
</Directory>

三．启动 

1.重启apache 

service httpd restart

2.重启smokeping 

/usr/local/smokeping/bin/smokeping restart

完成。
